It is the administrative and economical centre of Baranya County. Pécs is also the seat of the Roman Catholic Diocese of Pécs.

The Picture Exchange Communication System (PECS) is a form of augmentative and alternative communication produced by Pyramid Educational Consultants, Inc. While the system is commonly used as a communication aid for children with autism spectrum disorder (ASD), it has been used with a wide variety of learners, from preschoolers to adults, who have various communicative, cognitive, and physical impairments, including cerebral palsy, blindness, and deafness. PECS has been the subject of much academic research, with currently over 85 PECS-related publications.
